Abstract

The invention discloses a cloud SIM (subscriber identity module) capable of freely downloading network data. The cloud SIM comprises a network data downloading module, a key store, an operator database, a network data authentication module, an authentication module, a network selection module, a command interpretation module and an interface communication module. According to the scheme provided by the invention, subscribers can freely download network authentication data and network configuration data of an operator server, so the subscribers can use different operator networks through the same SIM card, the operation freedom degree of the subscribers is greatly improved, and in addition, the subscribers can download different network authentication data for handling different services, so the service handling efficiency of the subscribers is improved. Therefore, the cloud SIM provided by the invention has the advantages that different operator networks can be replaced for communication, so convenience is brought for users.

Description

technical field [0001] The invention relates to the technical field of SIM cards, in particular to a cloud SIM module capable of freely downloading network data. Background technique [0002] Usually, the mobile operator will bind the network authentication data with the SIM card of the mobile phone. [0003] When using this SIM card, the user cannot use the network of other mobile operators through this SIM card. For example, after the user selects the SIM card of mobile operator A, he can only use the network of mobile operator A for communication, but cannot use the network of other mobile operators for communication. The reason is that the mobile operator prohibits the user from downloading the network authentication data, and the existing SIM card cannot download the network authentication data. If the user wants to use the network of mobile operator B to communicate, he needs to replace the SIM card issued by mobile operator B. Therefore, the user cannot use the exi...
